In this embodiment, there are two guide rails 123, which are arranged parallel to each other. The movement tray 121 is provided with a groove that cooperates with the guide rails 123, so that the movement tray 121 can move along the guide rails 123, so as to utilize the guide rails 123. The sliding rails 123 reduce the frictional force during the movement of the moving tray 121, reduce the wear on the moving tray 121, and improve the service life.

The processing position is used for the fixture to stay, so as to place the first material, the second material and the third material on the fixture, so as to process the desired product. In a feasible manner, each processing position may correspond to a step in the processing procedure. For example, the processing position for stacking the first material, the second material and the third material may also be referred to as a loading position. Of course, in other feasible manners, two or more processing positions may correspond to one step in the process.

A second conveying mechanism and a detector are correspondingly disposed at each processing position, and the detector is used to detect whether the fixture reaches a position corresponding to the processing position during the movement with the first conveying mechanism 10 . The second conveying mechanism is used to disengage the jig from the first conveying mechanism 10 and move to the processing position when the corresponding detector detects the jig. For example, the second conveying mechanism may be a structure such as a lift cylinder, a hydraulic cylinder, etc., and the jig and the first conveying mechanism 10 are separated or contacted by the lifting and lowering of the second conveying mechanism.

Optionally, a photoelectric sensor for detecting whether the fixture is lifted in place is also provided on the top of the second conveying mechanism.

During the movement of the fixture with the first conveying mechanism 10, when detected by the detector A, it sends detection information indicating that the fixture is detected to the controller, and the controller controls the second conveying mechanism A to start according to the detection information, The second conveying mechanism A extends and pushes up the jig to separate it from the first conveying mechanism 10 and reaches the processing position. At this time, the first conveying mechanism 10 continues to move and convey other jigs. When the jig stays at the processing position, the material can be clamped by the first clamping part 40 and the second clamping part 70 and placed on the corresponding position of the jig.

When the first material, the second material and the third material are placed, and a processing position after the processing position is free, the controller can control the second conveying mechanism to shrink, so that the jig after the material is placed is lowered to On the first conveying mechanism 10, the first conveying mechanism 10 continues to move to the next processing position.

When the first material, the second material and the third material are placed, and a processing position after the processing position is not free (that is, there is a fixture), the controller determines that there are fixtures in the two adjacent processing positions. If the movement of the first conveying mechanism 10 cannot continue, the first conveying mechanism 10 is controlled to stop (for example, the frequency of the motor of the first conveying mechanism 10 is reduced to 0).

Optionally, in order to ensure that when the jig on the first conveying mechanism 10 reaches a position corresponding to the processing position, the jig can be blocked from passing through as required, a blocking component is further provided on the first conveying mechanism 10 . This allows the jig to be blocked with the blocking assembly when needed.

For example, in this embodiment, the blocking component includes a telescopic piece and a blocking piece, and the telescopic piece is provided on the first conveying mechanism 10 at a position corresponding to the processing position. The blocking member is rotatably arranged on the telescopic member through the blocking base, and moves up and down reciprocatingly under the driving of the telescopic member. In this embodiment, the detector is arranged on the blocking base, and the first end of the blocking member is matched with the telescopic member, and the second end of the blocking member is higher than the first end, so that when the fixture arrives, it will touch The second end of the blocking piece is rotated, and the first end of the blocking piece moves downward and touches the detector, and the detector detects that "the fixture is in place". The second conveying mechanism jacks up the jig.

When the operation on the jig is completed and the jig needs to pass, the second conveying mechanism descends so that the blocking component and the jig descend together. Afterwards, the retractable member shrinks, so that the blocking base and the blocking member are lowered relative to the jig together, and are separated from the jig, so that the jig can pass. At this time, the second end of the blocking member is no longer under the action of the jig, so the first end of the blocking member is separated from the detector.

Optionally, in order to make the jig pass through more easily, a roller is provided on the second end to reduce the frictional force when the jig passes.

According to another aspect of the present invention, a fuel cell stack assembly system is provided, which includes the above-mentioned feeding device. The fuel cell stack assembly system using the feeding device can automatically place the first material, the second material and the third material on the jig, thereby improving the automation degree of the production process, reducing the production cost, and ensuring the production quality.

Of course, implementing any technical solution of the embodiments of the present application does not necessarily need to achieve all the above advantages at the same time.

The expressions "first," "second," "the first," or "the second" as used in various embodiments of this application may modify various elements regardless of order and/or importance , but these expressions do not limit the corresponding parts. The above expressions are only used for the purpose of distinguishing an element from other elements. For example, a first user radiation therapy device and a second user radiation therapy device represent different user radiation therapy devices, although both are user radiation therapy devices. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present disclosure.

While the preferred aspects of the present application have been described, those skilled in the art may make additional changes and modifications to these once the basic inventive concepts are known. Therefore, the appended claims are intended to be construed to include the preferred and all changes and modifications that fall within the scope of this application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
